Wireless: support NL80211 userspace <-> kernelspace API
NL80211 was introduced in Linux 2.6.24 in 2007 as a new extensible
universal API, replacing "wireless extensions" ioctls. It works on top
of netlink, and allows direct communication to cfg80211 kernel
subsystem. Since then it became a hard requirement for all upstream
wireless drivers to hook into cfg80211 (SoftMAC drivers do it via the
common mac80211 layer). There's still additional compatibility code that
allows limited Wext functionality for cfg80211 drivers but it's buggy
and can be disabled altogether when CONFIG_CFG80211_WEXT is not set.
This patch makes use of "netlink" Haskell library which doesn't have any
additional runtime dependencies (so neither iwlib nor libnl are
required). The operation is the same as performed by "iw dev <devname>
link" command.
The signal level is transformed to "quality" by first clamping it to
[-110; -40], then adding 110 and dividing by 70 (same meaningless
formula as used by the cfg80211 Wext compatibility layer).
"essid" template argument is replaced by more appropriate "ssid" (with
the old variant still available for backwards compatibility)
